I'll definetely checkout that aem drop in. Any mpg gains? I'm assuming it's washable and lifetime?
It should be lifetime. AEM sells air filter cleaner in a spray bottle. I'd imaging if you clean the filer per AEM's recommendation, it will last the truck's lifetime. The filter itself is pretty robust construction. I dropped mine in about 2-3 weeks after having a new OEM filter installed (I did that so I have a clean OEM filter to swap for warranty work - just in case). I immediately noticed a slight throttle response increase, and the engine growl is a little more noticeable coming from the intake at WOT.
I haven't done anything remotely considered legitimate for a MPG test since, but I have a couple longer drives coming up in the next couple months. But it seems like my mileage is better. I've been averaging (mixed driving conditions) about 1mpg higher than I have ever had during my weekday work routine. My next 600 mile round trip drive should give me a better idea how much of an improvement it made.
For $40 (filter) and $15 (cleaner), I'd say it's a pretty good deal. Even with just a +1mpg net gain, the filter will pay for itself in less than 20 fill ups. And if you do what I did - keeping a clean OEM filter to swap in for oil changes/warranty work - you can watch, and laugh, at them try to up-sell you air filters you don't need.
